I get a strange error in my console when starting my application:
ImageIO: ERROR - MetadataLib.dylib not found
I'm not sure what this is connected with, but I am running AdMobs ads.
Yes, that's the answer from Apple. It looks like an error in the 4.1 SDK, which is addressed with the 4.2 SDK. In my code, it was called by a specific JPEG with a bunch of metadata. Updating to the latest SDK should fix the problem.
